Heirloom Auntie

A Goblin Warlock that shows up understrength and asks your other creatures to pay the difference: it enters carrying two -1/-1 counters, a shrunken version of the body on the type line, and each time another creature you control dies, you surveil 1 and shave a counter off. The design inverts the usual grindy-payoff timing. Rather than charge you up front for the full body or reward you only once it has survived a turn cycle, it enters cheap and undersized, then grows in the exact currency an aristocrats deck is already minting. Every death you were going to cause anyway (a token fed to a sacrifice outlet, a chump block, a trade you were happy to make) does double work, filtering your draws while lifting a counter toward the finished threat. The choice of -1/-1 counters rather than a clean growth clock has teeth: they interact with proliferate, with removal that shrinks toughness, and with anything that adds or wipes counters, so this is not the one-way ratchet a graveyard-scaling creature would hand you. The surveil is not ornamental either; it stocks the graveyard a sacrifice deck wants stocked, so unlocking the body and fueling the yard pull in the same direction. The result is a payoff whose activation cost is deaths you were spending regardless, tuned for the deck that treats its own board as ammunition rather than something to protect.
